Rewrite each expression as a polynomial in standard form: (2x^2 − x^3 − 9x +1) − (x^3 +7x − 3x^2 +1)

Polynomial in standard form will be

Step-by-step explanation:

We have given polynomial

We have to write this polynomial in standard form

For writing in standard form we have to first subtract the polynomial and then rearrange the order

So

So polynomial in standard form will be

i dony know

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
